. j The bin B, is .provided :in its bottom `with' a. hopper 36, while a horizontal conveyor 37 extends from this hopper to the conveyor E, so that material from the bin may be transferred to the conveyor and from this con- 5 veyor into the box 15 of the truck, in a manner to be described.

Extending from the upper end of the housing of the elevator E is a discharge spout 38. This spout has a swivel connection 39 lo with the housing so that its discharge end may be positioned over the bin B as shown in Figure 3 of the drawings, or it may be swung to the dotted line position in said figure.

1;, In unloading grain from the truck box 15, the drive wheels of the truck are positioned upon the rollers 24 with the front wheels of the truck elevated as shown in Figure 1. Operation of the drive wheels will operate the rollers and drive the conveyor 13, so that material falling from the truck will pass through the hopper 14 into the conveyor 13 and be carried to the lower end of the elevator. During the unloading .1'. operation, the lower end of the elevator housing upon the side adjacent the bin is closed by a plate 40. This plate is removably held in place by means of fastening devices 41, so that the material cannot pass horizontally 'ze through the elevator housing. The material will be carried upward by the conveyor buckets and directed by the discharge spout 38 into the bin. When it is desired to transfer material from the bin into the truck box :m 15, the plate 40 is removed and the shaft of the conveyor 37 is connected with the shaft of the conveyor 13 by means of a coupling 42. The truck is arranged as shown in Figure 2 of the drawings so that its drive wheels fe will operate the rollers 24 and drive the conveyor 37 and elevator E. The discharge spout 38 will be arranged as shown in the dotted line position in Figure 3 of the drawmgs.

43 The platform is provided with a transversely arranged plate 43 which extends over one of the rollers 24 of each pair and facilitates backing the truck from the rollers. The dog 27 will hold the rollers against retrograde rotation while the truck is being removed.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. In a power take-olf mechanism, a vehicle supporting platform, a bin at one side thereof, a hopper beneath the platform to receive material from the vehicle upon said platform, an elevator between the hopper and bin, a conveyor extending from the hopper to the elevator, a hopper in the bottom of the bin,

a conveyor extending from the bin hopper to the elevator, a discharge spout extending from the conveyor to direct material either into the hopper or into a vehicle upon the platform, and means operated by a vehicle upon the platform to drive the conveyor and elevator.

2. In a power take-off mechanism, a vehicle supporting platform, spaced shafts mounted beneath the platform, a bin at one side of the platform, a hopper beneath the platform to receive material from the vehicle upon said platform, an elevator between the hopper and bin, a conveyor extending from the hopper to the elevator, a hopper in the bottom of the bin, a conveyor extending from the bin hopper to the elevator, a discharge spout extending from the conveyor to direct material either int-o the hopper or into a vehicle upon the platform, and spaced means mounted on said shafts and operated by a vehicle on the platform to drive the conveyor and elevator.

3. In a power take-off mechanism, a vehicle supporting platform, spaced shafts mounted beneath the platform, a chain-driven connection lbetween said shafts, a bin at one side of the platform, a hopper beneath the platform to receive material from the vehicle upon said platform, an elevator between the hopper and bin, a drive connection between one of said shafts and said elevator, a conveyor extending from t-he hopper to the elevator, a hopper in the bottom of the bin, a conveyor extending from the bin hopper to the elevator, a discharge spout extending from the conveyor to direct material either into the hopper or into a vehicle upon the platform, and spaced rollers mounted on said shafts and operated by a vehicle on the platform to drive the conveyor and elevator.

In testimony whereof I affix my simature.
